Suitability: 11/10
This is very, very useful because I now produce more milk. I used to only produce 1-2oz, but after 2 weeks of using this, I now produce 4-7oz! My nipples don't hurt anymore. My girls don’t like too much pressure from the pump, so I added this item to the flange to prevent discomfort while pumping. VERY EFFECTIVE. I will definitely order more!
